Note: continuous time signals x(t), time t = R+; and its Laplace transform result is (s) where s Z. Consider the following small angle 0(t) pendulum system ml + mg0 = 0 with initial conditions as 0 (0) = 00, 0 (0) = wo. Use both (a) time-domain method and (b) s-domain method to find its solution. Note: both of them should be the same. You may use wn g/l to simplify your answer. The parameters are all positive real numbers including mass m, pendulum length 1, and gravity constant g. =
